Question

Suppose we use RANDOMIZED-SELECT to select the minimum element
of the array A = **{12, 0, 4, 3, 5, 7, 9, 2, 8, 11}**.
Describe a sequence of partitions that results in a worst-case
performance of RANDOMIZEDSELECT.

Answer #1

**Q.Suppose we use RANDOMIZED-SELECT to select the minimum
element of the array A = {12, 0, 4, 3, 5, 7, 9, 2, 8, 11}. Describe
a sequence of partitions that results in a worst-case performance
of RANDOMIZEDSELECT.**

**Answer:**

In the example, the sequence would be{ 12,11,9,8,7,5,4,3,2,0 }

- pivot
**12 {**0,4,3,5,7,9,2,8,11} - pivot
**11**{0,4,3,5,7,9,2,8} - pivot
**9**{0,4,3,5,7,2,8} - pivot
**8**{0, 4, 3, 5,7,2 } - pivot
**7**{0, 4, 3, 5, 2} - pivot
**5**{0, 4, 3, 2} - pivot
**4**{0, 3, 2} - pivot
**3**{0, 2} - pivot
**2**{0} - return 0

We are given an array A of size n containing n positive and
negative integers (the array is indexed starting from 0).
Our goal is to find two indices i and j such that 0 ≤ i ≤ j ≤ n
and Pk=j k=i A[k] is maximized.
Input sequence: [2, -4, 1, 9, -6, 7, -3]
Output: [1, 9, -6, 7] or i = 2 and j = 5
Input sequence: [1, 2, 3, 4, 5, 6, -3]
Output: [1,...

Use the following to answer the questions below:
Below are the marginal costs of abating pollution for three
firms in an industry, based on their emissions levels. Each firm is
now emitting 10 tons/week, so total emissions are 30 tons/week.
Suppose we wish to reduce total emissions by 50 percent, to 15 tons
per week in this industry.

Suppose we consider a bus "old" if it has been in service more
than 8 years. At the 0.01 significance level, can we conclude that
less than 40% of the district's buses are old? Report the

(Data Structure)
Suppose we want to store the data of
a binary heap in an array. Show the data of that array after
inserting the given keys one by one. Assume that initially binary
heap is empty. Show all steps of insertions.
Note: No need to show the changes for
each step of “percolate up”. The contents of the array must be
shown after completing one insertion.
Create the “Min Heap” for the
following data set
7,
3, 18,
-9, ...

Use = .05 to test for any significant differences. Show entries
to 2 decimals, if necessary. Round p-value to four decimal places.

A manager at a local discount gym believes that less than 20% of
gym members use the gym, at least 5 days a week. She randomly
selects 100 gym members and tracks (using the electronic login
system at the door) how many days they used the gym over the 2-week
period. The following are the results:

USE C++
Write a sum() function that is used to find the sum of the array
through pointers. In
this program we make use of * operator. The * (asterisk) operator
denotes the
value of variable.
Input: array = 2, 4, -6, 5, 8, -1
Output: sum = 12
